Output Level Adjustment

With Source Signals

Normal output level adjustment for the

AVR is established using the test tone, as out-

lined on page 36. In some cases, however, it may

be desirable to adjust the output levels using

program material such as a test disc, or a selec-

tion you are familiar with. Additionally, the out-

put level for the subwoofer and those for the

Stereo modes can only be adjusted using this

procedure. Note that all adjustments made with

any input will be effective with all inputs select-

ed, just as it is the case with the adjustment

using the test tone.

To adjust the output levels using program materi-

al, first select the surround mode for which you

want to trim the speakers (see NOTE below), start

your program material source and set the

reference volume for the front left and front right

channels using the Volume Control

Once the reference level has been set, press the

Channel Select button

and note that

FRONT L LEVEL will appear in the Lower

Display Line

. To change the level, first

press the Set button

, and then use the

Selector buttons

or the

⁄

buttons

to raise or lower the level. DO NOT use the

volume control, as this will alter the reference

setting.

Once the change has been made, press the Set

button

and then press the Selector but-

tons

or the

⁄

buttons

to select

the next output channel location that you wish to

adjust. To adjust the subwoofer level, press the

Selector buttons

or the

⁄

buttons

until WOOFER LEVEL appears in the

Main Information Display

or on-screen

display (only available if the subwoofer is turned

on).

Press the Set button

when the name of

the desired channel appears in the Main

Information Display

and on-screen

display, and follow the instructions shown above

to adjust the level.

Repeat the procedure as needed until all

channels requiring adjustment have been set.

When all adjustments have been made and no

further adjustments are made for five seconds,

the AVR will return to normal operation.

The channel output may also be adjusted using

the full-OSD on-screen menu system. First, set

the volume to a comfortable listening level using

the Volume Control

I. Then, press

the OSD button

to bring up the MASTER

(Figure 7). Press the

Button

four

times until the on-screen ➞ cursor is next to

the

MANUAL SETUP line. Press the Set

Button

, select the CHANNEL ADJUST

line and press the Set Button

to activate the

CHANNEL ADJUST menu (Figure 22).

Figure 22

When the menu appears, the internal test tone

will be turned off.This will allow you to use your

external test disc or other source material as the

test signal. Then, use the

⁄

Buttons

select the channels to be adjusted. At each

channel position use the

‹

›

Buttons

change the output level.

Remember, when you are using a disc with test

signal (e.g. pink noise) or an external signal

generator as the source, the goal is to have the

output level at each channel be equal when

heard at the listening position, with any surround

mode selected. When your test source is a

normal disc with music signals, you may adjust

the level for each channel and surround mode as

you prefer, e.g. you may lower the center channel

level when you find it to be too high or increase

the level of the rears when you find it to be too

low with specific surround modes.

If you wish to reset all the levels to their original

factory default of 0dB offset, press the

⁄

Buttons

so that the on-screen cursor is

next to the

LEVEL RESET line and press

the

‹

›

Buttons

so that the word ONis

highlighted. After the levels are reset, resume the

procedure outlined above to reset the levels to

the desired settings. When all adjustments are

done, press the

⁄

Buttons

to move the

on-screen ➞ cursor so that it is next to

BACK

TO MANUALSETUP

and then press the

Set Button

if you wish to go back to the

main menu to make other adjustments. If you

have no other adjustments to make, press the

OSD Button

to exit the menu system.

NOTE: The output levels may be separately

trimmed for each digital and analog surround

mode. If you wish to have different trim levels for a

specific mode, select that mode and then follow the

instructions in the steps shown above.

With Stereo modes the adjustment procedure

described above is the only way to trim the out-

put level, e.g. to match the Stereo level with

other modes.

EzSet/EQ On/Off

If you wish to turn the filter settings established

by EzSet/EQ on or off to demonstrate the impact

EzSet/EQ has on the sound of your system,

simply press the EzSet/EQ On/Off button

Using this feature does not change the settings;

it merely puts them in or out of the signal path.

Dim Function

Since the AVR will often be used when movies or

other video programming is viewed under low-

light conditions, you may wish to lower the

brightness of the front-panel displays and indica-

tors so that they do not distract from the video

presentation. You may dim the displays using the

menu system, as shown on page 47, or you may

control the brightness directly from the remote.

Simply press the Dim Button

once to dim

the front panel to half the normal brightness

level; press it again to turn the displays off. Note

that when the displays are dimmed or turned off,

the blue lighting around the Standby/On

Switch

will continue to stay lit as a reminder

that the AVR is still turned on.

The accent lighting for the Volume Control

will remain at its normal level, rather than dim

when the panel displays are at half brightness.

Note that all changes to the front-panel bright-

ness level are temporary; the displays will return

to full brightness after the AVR is turned off and

then on again. To return the displays to full

brightness without turning the unit off, press the

Dim Button

as needed until the displays

are on.

In addition to lowering the brightness of the

displays or turning them off completely, you may

wish to have them appear whenever a button on

the remote or front panel is pushed, and then

gradually fade out after a set time period. You

may do this by making the appropriate settings in

the

VFD FADETIMEOUT line of the

ADVANCED SELECT menu, as shown on

page 47.

Memory Backup

This product is equipped with a memory backup

system that preserves tuner presets and system

configuration information if the unit is turned off

completely, accidentally unplugged or subjected

to a power outage. This memory will last for

approximately two weeks, after which time all

information must be reentered.
